Dirk Gently's Schrödinger's cat

You crate a wooden box containing a cat. The cat is dead and alive until the box is opened. Roll a d100. on 1-50 the cat is alive on a 51-100 the cat is dead. Roll another d100 on 15, 28, 52, 67, 72 and 98 the cat is not in the box and appears at any point of space-time the DM chooses. If the box is opened the spell is triggered and its therrible power is or is not released. Roll a d100 on a 1-50 the spells power is released on a 51-100 it is not. If the spells power is released everything in a 120ft sphere centered on the box is affected. An affected object such as a tree or the ground has a 50% chance of existing. Roll a d100. on a 1-50 the object doesent exist on a 51-100 it does. An affected creature has a 50% chance on succeeding and failing in any deed it does. Instead of rolling an attack roll, saving throw or an ability check a creature that is affected rolls a d100 (1-50 fail, 51-100 success)or flips a coin or does something that has a 50-50 chance. A creature that casts a spell and is affected he/she must roll a d100. On a 1-50 the spell isn't casted, the spell slot is saved and the action is wasted. The cat acts or doesen't act like a normal cat would. Roll a d100. On a 1-50 it acts as usual on a 51-100 it doesn't.
